The peculiar sensation often described as ‘sparkling water’ fizzing in the legs might seem strange, but it could be a key symptom of a neurological condition known as restless legs syndrome (RLS), or Willis-Ekbom disease. This disorder makes it extremely challenging for people to remain still, mainly because of uncomfortable feelings in the limbs.
Individuals with RLS typically experience burning, cramping, throbbing, or tingling sensations in their legs, often compared to fizzy water bubbling beneath the skin. These sensations come with an irresistible urge to move the affected limbs, which provides only temporary relief.
Many sufferers also experience periodic limb movements (PLM), characterized by involuntary jerking or twitching of the legs, and sometimes the arms, particularly during sleep. These movements often occur every 20 to 40 seconds and can be so severe that they wake not only the individual but also their partner.

The symptoms of RLS and PLM can range from mild to severe and typically worsen during nighttime, significantly disrupting sleep quality. As a result, those affected may endure daytime sleepiness, fatigue, and mood disturbances.
While the exact cause of RLS often remains unknown, it may sometimes signal more serious health issues such as iron deficiency, kidney failure, Parkinson’s disease, or spinal problems.
For many with no underlying conditions, simple lifestyle adjustments can help manage symptoms. These include regular exercise, avoiding caffeine and alcohol, and maintaining a consistent sleep schedule.
During intense episodes involving leg jerks, patients are encouraged to move their limbs or walk to relieve discomfort. If symptoms severely disrupt sleep, a healthcare professional may recommend a short-term course of hypnotic medications, such as zopiclone or zolpidem, which are typically prescribed for no longer than a week.
Recognizing these sensations early and seeking appropriate guidance can significantly improve quality of life for those affected by Willis-Ekbom disease.
